Product details
Overview
TLE8203EXUMA1 from Infineon Technologies is a triple-channel high-side power switch IC designed for automotive mirror actuator control, featuring 3× independent 0.7 A rated channels, integrated current sense (±5% accuracy), thermal shutdown, and diagnostic feedback via open-load and overtemperature flags. It operates from 5.5 V to 28 V supply and supports PWM input control for precise position adjustment in electric side-view mirror systems.
For engineers reviewing the TLE8203EXUMA1 datasheet, TLE8203EXUMA1 pinout, TLE8203EXUMA1 application, or TLE8203EXUMA1 equivalent, key selection criteria include channel independence, integrated diagnostics, current-sense linearity, SOA compliance under pulsed load, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
The TLE8203EXUMA1 integrates three fully independent high-side switches with dedicated enable inputs (IN1–IN3), each driving resistive or inductive mirror motor loads. Each channel includes real-time current sensing with analog output (I_SENSEx) scaled at 1 V/A and fault reporting via shared DIAG pin.
It implements adaptive slew-rate control to limit EMI during switching, supports 100% duty-cycle operation, and features internal charge pump for gate drive above supply rail-enabling robust conduction even at low battery voltages down to 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 28 V: Supports full automotive battery range including cold-crank (6.0 V) and load-dump (28 V) conditions without external protection. |
| Max Output Current per Channel | 0.7 A DC continuous: Sufficient to drive dual-coil mirror actuators with margin for stall current and temperature derating. |
| Current Sense Accuracy | ±5% over -40°C to +150°C: Enables reliable open-load detection and closed-loop current monitoring without calibration. |
| Diagnostic Outputs | Open-load, overtemperature, short-to-ground: Reported via active-low DIAG pin with priority encoding for fault isolation. |
| Switching Frequency Support | DC to 100 Hz PWM: Matches typical mirror positioning update rates while maintaining thermal stability and EMI control. |
| AEC-Q100 Qualification | Grade 1 (-40°C to +125°C ambient): Validated for engine compartment proximity mounting in passenger vehicles. |
Pinout & Package
Package: DSO-36 (36-pin exposed-pad thermally enhanced SOIC), 15.0 mm × 10.0 mm × 2.4 mm body, pitch 0.8 mm, thermal pad soldered to PCB ground plane for RθJA ≤ 35 K/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to 12 V battery rail; internal clamp protects against transients up to 40 V. |
| GND | Power and signal reference | Dual GND pins (pins 1, 36) and thermal pad ensure low-impedance return path for all three channels. |
| IN1–IN3 | Independent channel enable inputs | TTL/CMOS-compatible; each controls one high-side switch without cross-talk or shared logic dependency. |
| OUT1–OUT3 | High-side switched outputs | Each drives mirror motor coil directly; no external flyback diode required due to integrated clamp. |
| I_SENSE1–I_SENSE3 | Analog current monitor outputs | 1 V/A scaling enables direct ADC interface for real-time load current measurement per channel. |
| DIAG | Shared fault indicator | Active-low open-drain output encodes highest-priority fault (open-load > overtemp > short-to-GND). |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent high-side switches | Enables simultaneous or staggered control of vertical/horizontal mirror motors and heater elements without resource contention. |
| Integrated current sense with ±5% accuracy | Eliminates need for external sense resistors and amplifiers, reducing BOM count and layout area by ≥4 components per channel. |
| Thermal shutdown with hysteresis | Triggers at 175°C junction, releases at 155°C-prevents latch-up during transient overload while allowing recovery without MCU intervention. |
| Diagnostic flag prioritization | Hardware-encoded fault reporting avoids software polling delays and ensures deterministic response to critical failures. |
Applications
| Electric Side-View Mirror Control | Auto-Dimming Mirror Actuation |
|---|---|
Use Scenario: Precise angular positioning of left/right exterior mirrors via dual-axis stepper or DC motor control. IC Role / Device Role / Timing Role: High-side driver for H-bridge half-bridge legs, providing directional current control and real-time load feedback. Use Value: Enables closed-loop position correction using I_SENSEx signals, improving mirror alignment repeatability to ±0.5° over lifetime. | Use Scenario: Dynamic tilt adjustment of electrochromic rearview mirrors based on glare sensor input. IC Role / Device Role / Timing Role: Power switch for mirror tilt motor and integrated heater element, coordinated via CAN-triggered enable sequencing. Use Value: Reduces system latency to <100 ms from command to full tilt motion, meeting OEM response time requirements. |
| Heated Mirror Element Control | Multi-Axis Camera Mount Positioning |
Use Scenario: On-demand heating of mirror glass surface to prevent fogging or icing in cold/humid climates. IC Role / Device Role / Timing Role: High-side switch for PTC heater trace, controlled via PWM duty cycle to regulate surface temperature. Use Value: Maintains mirror surface at 25–35°C using 0.5 A @ 12 V, avoiding thermal runaway via built-in overtemperature lockout. | Use Scenario: Stabilized positioning of ADAS camera housings mounted on mirror assemblies. IC Role / Device Role / Timing Role: Driver for precision piezo or voice-coil actuators requiring low-noise, ripple-free current sourcing. Use Value: Delivers <1% current ripple at 50 Hz PWM, minimizing image jitter in 1080p video capture during vehicle vibration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple high-side motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS724G | Single-channel 2.5 A high-side switch; no integrated current sense; requires external sense resistor and comparator. | Lacks multi-channel integration and diagnostics-requires 3× devices plus support circuitry for same functionality. | Select when higher per-channel current (2.5 A) is needed and board space allows discrete implementation. |
| TPS4H160-Q1 | Quad-channel 1.6 A high-side switch with SPI interface and configurable diagnostics; no analog current sense outputs. | Supports programmable fault thresholds and channel grouping but adds MCU communication overhead. | Select when centralized configuration and logging via CAN/SPI are required over analog simplicity. |
Compared with BTS724G and TPS4H160-Q1, the TLE8203EXUMA1 delivers optimal balance of channel integration, analog current visibility, and minimal external component count for cost-sensitive, space-constrained mirror modules requiring deterministic diagnostics.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TLE8203EXUMA1 has a maximum junction temperature of +175°C, with thermal shutdown activating at this threshold. Continuous operation is rated up to +150°C junction under specified load and PCB copper area conditions. Derating curves in the datasheet define safe operating area limits for pulsed currents above 0.7 A.
Does the device support PWM dimming or speed control for mirror motors?
Yes-each INx input accepts PWM signals up to 100 Hz with 50 ns minimum pulse width. The internal gate driver maintains consistent on-resistance and rise/fall times across duty cycles, enabling smooth motor speed regulation without audible noise or torque ripple.
How is open-load detection implemented and what is its response time?
Open-load detection uses internal current comparators that monitor voltage drop across the channel's sense FET. Detection activates within 10 µs of load removal and asserts the DIAG pin within 20 µs. No external components are required, and the function remains active during both ON and OFF states.
Can the TLE8203EXUMA1 be used without connecting the thermal pad?
No-the exposed thermal pad is electrically connected to GND and is mandatory for thermal performance and electrical integrity. Omitting solder connection increases RθJA by >60%, causing premature thermal shutdown at ≤0.4 A/channel and violating AEC-Q100 thermal test conditions.
